A frictionless piston-cylinder assembly initially contains B m3 of air at A kPa pressure. In this state, a linear spring touches the piston but does not exert any force. Then the air is heated and the piston moves up. Finally, the volume is C m3  and the pressure is D kPa. a) Draw the state change PV diagram, b) Calculate the total work done by the air (kJ), c) Calculate the work done against the spring (kj).

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.
